* Initial fixes for bug #85.Gravatar Hauke Heibel2010-10-25
| | | | | | | Renamed meta_{true|false} to {true|false}_type, meta_if to conditional, is_same_type to is_same, un{ref|pointer|const} to remove_{reference|pointer|const} and makeconst to add_const. Changed boolean type 'ret' member to 'value'. Changed 'ret' members refering to types to 'type'. Adapted all code occurences.
* bug #86 : use internal:: namespace instead of ei_ prefixGravatar Benoit Jacob2010-10-25

|
* Add blocking inside HouseholderQR based on code from Vincent Lejeune.Gravatar Gael Guennebaud2010-06-17
| | | | This is all internal stuff for now.
* * Make HouseholderSequence::evalTo works in placeGravatar Gael Guennebaud2010-06-10
| | | | | | | | | | * Clean a bit the Triadiagonalization making sure it the inplace function really works inplace ;), and that only the lower triangular part of the matrix is referenced. * Remove the Tridiagonalization member object of SelfAdjointEigenSolver exploiting the in place capability of HouseholdeSequence. * Update unit test to check SelfAdjointEigenSolver only consider the lower triangular part.
* * remove ei_index, and let ei_traits propagate the index typesGravatar Gael Guennebaud2010-06-03
| | | | * add an Index type template parapeter to sparse objects
* the Index types change.Gravatar Benoit Jacob2010-05-30
| | | | As discussed on the list (too long to explain here).
* Respect MaxRowsAtCompileTime in HouseholderSequence::evalTo().Gravatar Jitse Niesen2010-05-25
| | | | | This fixes the failing test nomalloc_4. Also remove a print inserted for debugging in schur_real test.
* * implement the corner() API change: new methods topLeftCorner() etcGravatar Benoit Jacob2010-04-22
| | | | | | | | * get rid of BlockReturnType: it was not needed, and code was not always using it consistently anyway * add topRows(), leftCols(), bottomRows(), rightCols() * add corners unit-test covering all of that * adapt docs, expand "porting from eigen 2 to 3" * adapt Eigen2Support
* oos, remove eval() used for debuggingGravatar Benoit Jacob2010-04-19

* * Refactoring of the class hierarchy: introduction of DenseDirectAccessBase, ↵Gravatar Benoit Jacob2010-04-16
| | | | | | | | | removal of extra _Base/_Options template parameters. * Introduction of strides-at-compile-time so for example the optimized code really knows when it needs to evaluate to a temporary * StorageKind / XprKind * Quaternion::setFromTwoVectors: use JacobiSVD instead of SVD * ComplexSchur: support the 1x1 case

* * Fix #97 : Householder operations on 1x1 matricesGravatar Benoit Jacob2010-03-08
| | | | | * Fix VectorBlock on 1x1 "vectors" * remove useless makeTrivialHouseholder function
* Renamed PlainMatrixType to PlainObject (Array != Matrix).Gravatar Hauke Heibel2010-02-20
| | | | Renamed ReturnByValue::ReturnMatrixType ReturnByValue::ReturnType (again, Array != Matrix).
* Renamed AnyMatrixBase to EigenBase.Gravatar Hauke Heibel2010-02-20

* fix a couple of ICE with gcc 4.0.1Gravatar Gael Guennebaud2010-02-12

* allow to multiply a householder sequence and a matrix when one is real and ↵Gravatar Benoit Jacob2010-01-15
| | | | | | one is complex. This is especially important as in bidiagonalization, the band matrix is real.
* Introduce third template parameter to HouseholderSequence: int Side.Gravatar Benoit Jacob2010-01-14
| | | | | When it's OnTheRight, we read householder vectors as rows above the diagonal. With unit test. The use case will be bidiagonalization.

| | | | | | | | | EIGEN_SIZE_MIN instead of EIGEN_ENUM_MIN, and there are many other occurences throughout Eigen! * HouseholderSequence: - add shift parameter - add essentialVector() method to start abstracting the direction - add unit test in householder.cpp

| | | | | | | | being wrong could bypass the other condition in the &&. at least that's my explanation why the test_lu was often failing on complex matrices (it uses that via createRandomMatrixOfRank) and why that's fixed by this diff. also gcc 4.4 gave a warning about tailSqNorm potentially uninitialized
